Aircraft services vary vastly from airport-to-airport. Generally speaking, the bigger the airport, the more options they’ll offer. Options can include aircraft cleaning, aircraft handling, aircraft maintenance, aircraft parking, aircraft toilet maintenance, aircraft towing, aircraft water replenishment, baggage waste disposal, baggage & freight handling, catering, chocking, de-icing, equipment hire (such as tugs or airside vehicles), executive lounge access (FBO), flight planning, Ground Power Unit (GPU) connections, hangarage, marshalling, meeting and conference room facilities, pushback, ramp facilities, refuelling, replenishments (such as oxygen and other gasses). When looking for a service provider, you may wish to consult a Flight Support Company, who will be able to search and find the most appropriate and cost-effective option at each airport.
